# [LeetCode] Top Interview 150 Problems Solving # 58 Length of Last Word

# **Understanding the Problem**

A string is given. It has spaces in between. The task is to return the last string’s length. If the string is `s = “Hello world”`, the last string will be `”world”` and its length will be 5, so return 5.

# **Approach**

My approach will be to `split()`, get the last index and return length of it.

# **Solution**

It was a simple problem. It would take a few lines without any help of the internal functions but it took one line with it.

First, split the string by space, then get the last index with `[-1]`, then get the length of the last index with `len()`.

```python
class Solution:
    def lengthOfLastWord(self, s: str) -> int:
        return len(s.split()[-1])
```

# **Reflection**

Nothing much to say about this. I was happy to see that this kind of a problem could show in interviews.
